Can Your Employer Sack You for Private Social Media Posts? Lessons from Higgs v Farmor's School

In February 2025, the Court of Appeal handed down one of the most significant employment law judgments in recent years. Higgs v Farmor's School [2025] EWCA Civ 109 concerned a school employee dismissed for Facebook posts made on her personal account, outside of work hours, under a name her employer did not recognise. The Court found her dismissal was unlawful discrimination. But the case is not simply about social media policies or the rights of Christians in the workplace. It is about something more fundamental: the extent to which the law protects what you believe, how you express it, and when your employer can punish you for doing so.

This article sets out the legal framework governing philosophical and religious belief protection under the Equality Act 2010, traces the full procedural history of Higgs, analyses the Court of Appeal's reasoning, and draws out the practical implications for workers and employers alike.

The Legal Framework: Belief as a Protected Characteristic

Section 10 of the Equality Act 2010

Under section 10 of the Equality Act 2010, religion or belief is a protected characteristic. "Belief" includes any religious or philosophical belief, and a reference to belief includes a reference to a lack of belief. The Act protects individuals from direct discrimination, indirect discrimination, harassment, and victimisation on the grounds of that characteristic under sections 13, 19, 26, and 27 respectively.

The Act does not define what counts as a qualifying belief. That task fell to the courts.

The Grainger Criteria

The leading authority on what constitutes a protected philosophical belief is Grainger plc v Nicholson [2010] ICR 360, in which Employment Judge Underhill (as he then was, before his elevation to the Court of Appeal) set out five criteria. A belief must:

Be genuinely held.
Be a belief, not merely an opinion or viewpoint based on present information.
Be a belief as to a weighty and substantial aspect of human life and behaviour.
Attain a certain level of cogency, seriousness, cohesion, and importance.
Be worthy of respect in a democratic society, not be incompatible with human dignity, and not conflict with the fundamental rights of others.

The fifth criterion functions as a threshold filter. It does not require the belief to be universally accepted or uncontroversial. As the courts have confirmed, unpopular and even offensive beliefs can still be protected, provided they do not cross into territory that undermines the basic dignity of other human beings.

The Expanding Scope of Protection

Since Grainger, the courts and tribunals have found a wide range of beliefs to qualify. Ethical veganism was recognised as a protected philosophical belief in Casamitjana v League Against Cruel Sports [2020] (Employment Tribunal, Norwich). A belief in the sanctity of life qualified in Hashman v Milton Park (Dorset) Ltd [2011] (ET). Most prominently, gender-critical beliefs, including the belief that biological sex is immutable and that it cannot be changed by gender reassignment, were found to meet the Grainger criteria in Forstater v CGD Europe [2021] IRLR 706, a judgment upheld by the Court of Appeal in Forstater v CGD Europe [2022] EWCA Civ 1004.

Not every strongly held view qualifies. In Gray v Mulberry Company (Design) Ltd [2019] EWCA Civ 1370, a belief in the statutory human right to copyright in one's own creative works was found too specific and insufficiently weighty to qualify. The Grainger criteria require a belief that forms part of a broader worldview, not a reaction to a specific situation or a personal interest dressed up in philosophical language.

Higgs v Farmor's School: The Facts

Kristie Higgs was employed as a pastoral administrator and work experience manager at Farmor's School in Gloucestershire. She had worked there for approximately six years without any complaints about her conduct or performance.

In October 2018, a parent wrote to the school's headteacher complaining about posts Mrs Higgs had shared on her personal Facebook page. She used her maiden name on that account. The posts, mostly re-shared from other sources, criticised government policy on relationships and sex education in primary schools. Two themes were prominent: opposition to the teaching that gender is fluid and not binary, and the view that same-sex marriage cannot be equated with marriage between a man and a woman. Neither post was directed at any pupil, parent, or colleague. Neither identified her as an employee of the school. The account was in her maiden name and visible only to her personal network. The school had no prior awareness of the account's existence.

The school suspended Mrs Higgs pending investigation. Following a disciplinary hearing in December 2018, she was summarily dismissed for gross misconduct in January 2019. The school's stated concern was reputational: it feared that the posts, if associated with the school, would damage its standing with parents and the wider community, particularly in relation to its LGBT pupils and families.

Mrs Higgs brought claims in the Employment Tribunal for direct discrimination and harassment under sections 13 and 26 of the Equality Act 2010, on the grounds of religion or belief. Her protected beliefs were her Christian faith and her related beliefs that biological sex is binary and immutable, and that marriage is properly understood as a union between a man and a woman.

The Procedural Journey

Employment Tribunal

The Employment Tribunal dismissed Mrs Higgs' claims. It found that she had not been dismissed because of her beliefs but because of the manner in which she had expressed them. In the Tribunal's analysis, the school's concern was the potential for reputational harm, not the substance of what she believed. The beliefs themselves were treated as incidental.

This reasoning was flawed in a way the EAT would later identify as a fundamental legal error.

Employment Appeal Tribunal: Higgs v Farmor's School [2023] EAT 89

Mrs Higgs appealed. The Employment Appeal Tribunal, presided over by Mrs Justice Eady (President of the EAT), allowed her appeal. The EAT found that the Employment Tribunal had failed to ask the correct legal question. The Tribunal had not considered whether the Facebook posts were themselves a manifestation of Mrs Higgs' protected beliefs, and if so, whether the school's decision to dismiss her was because of, or materially influenced by, those protected beliefs.

The EAT remitted the case to the Employment Tribunal for reconsideration. Mrs Higgs appealed this decision on the basis that the EAT was in a position to determine the claim itself without sending it back to a tribunal that had already erred.

Court of Appeal: Higgs v Farmor's School [2025] EWCA Civ 109

Both parties appealed to the Court of Appeal. The panel comprised Lord Justice Underhill (Vice-President of the Court of Appeal, Civil Division), Lord Justice Bean, and Lady Justice Falk. The judgment was handed down on 12 February 2025.

"The dismissal of an employee merely because they have expressed a religious or other protected belief to which the employer, or a third party with whom it wishes to protect its reputation, objects will constitute unlawful direct discrimination within the meaning of the Equality Act."

Lord Justice Underhill, Higgs v Farmor's School [2025] EWCA Civ 109

The Court allowed Mrs Higgs' appeal, set aside the remittal, and substituted judgment in her favour. The school's dismissal of Mrs Higgs was held to constitute unlawful direct discrimination.

The Supreme Court subsequently refused permission to appeal. The Court of Appeal judgment therefore stands as the definitive legal authority on the questions it addressed.

The Court of Appeal's Reasoning

The Belief vs Manifestation Distinction

The central analytical challenge in cases of this kind is the relationship between holding a protected belief and expressing or manifesting it. The Equality Act protects the belief itself. It does not provide blanket protection for every act done in the name of that belief. An employer who disciplines an employee for conduct that happens to be connected to a belief is not automatically discriminating on grounds of that belief. The question is whether the treatment was materially influenced by the protected characteristic.

The Employment Tribunal had treated the manner of expression as separable from the belief, concluding that the school's concern was with the reputational risk of the posts rather than with Mrs Higgs' beliefs per se. The Court of Appeal rejected this analysis. The posts were a direct expression of her protected beliefs. You cannot meaningfully separate the act of expressing a belief from the belief itself where the act is simply the articulation of that belief in words.

The Proportionality Framework

Even where an employer acts because of a manifestation of belief, that treatment is not automatically unlawful. The Court confirmed that an employer may impose restrictions on the manifestation of a protected belief where those restrictions are proportionate to a legitimate aim. This framework, derived from Article 9(2) of the European Convention on Human Rights, applies directly to belief cases under the Act.

The Court identified the relevant questions as:

Was the treatment because of, or materially influenced by, the manifestation of the protected belief?
If yes, did the treatment pursue a legitimate aim?
Was the treatment proportionate to that aim?

Applying this framework to the facts, the Court found that the school had failed at the third stage. The dismissal was not proportionate. Several factors were significant:

Mrs Higgs had worked at the school for six years without complaint. There was no suggestion she had allowed her personal views to affect her work with pupils, including LGBT pupils.
The posts were made on a personal account under her maiden name. There was no direct link between the posts and the school.
The school could have responded to any reputational risk by issuing a statement distancing itself from her personal views. Dismissal was the most severe sanction available and was disproportionate in the circumstances.
The posts, while containing language the Court acknowledged was at points intemperate and capable of causing offence (including references to "brainwashing" and to the "LGBT crowd"), were not directed at any identifiable individual or group and were not primarily designed to incite hatred or disgust. The Court accepted the school's concern about tone but found it insufficient to justify dismissal.

As the Court put it, the posts were "a long way" from the kind of expression that could justify the extreme sanction of dismissal.

The Reputational Risk Argument

The school's primary justification was reputational harm: the risk that parents of LGBT pupils would associate Mrs Higgs' personal views with the school and withdraw confidence in its ability to safeguard those pupils. The Court did not dismiss this as an illegitimate concern. Protecting the interests and wellbeing of pupils, including LGBT pupils, is plainly a legitimate aim.

However, legitimate aim is not sufficient. The question is whether dismissal was a proportionate means of achieving it. Here, the Court found it was not. The connection between Mrs Higgs' personal Facebook posts and actual harm to the school's reputation or to its pupils was too remote and speculative to justify the most serious sanction an employer can impose.

This aspect of the judgment has significant broader implications. It establishes that an employer cannot rely on vague or hypothetical reputational risk as a proportionate justification for dismissing an employee whose out-of-work expression of belief causes discomfort or controversy.

Belief vs Expression: Where Does Protection End?

Higgs is not a licence for employees to say whatever they like. The proportionality framework the Court applied is real and operative. The outcome might have been different if the posts had been more extreme, if they had been linked directly to the school, if there had been prior complaints about Mrs Higgs' conduct with pupils, or if the language had been designed to harass or demean rather than to argue a point.

The case sits in a line of authority that includes Forstater and Mackereth v Department for Work and Pensions [2022] EAT. In Mackereth, a Christian doctor refused to use transgender pronouns with patients. The EAT found that his gender-critical and Christian beliefs qualified as protected, but that the DWP's requirement to use preferred pronouns was a proportionate means of pursuing the legitimate aim of providing a service without discrimination or harassment. The belief was protected; the specific conduct was not.

The emerging principle is that the law distinguishes between:

The belief itself: broadly protected under Grainger, with a relatively low threshold that does not require social acceptability.
The expression of that belief in context: subject to proportionality analysis, with the outcome depending on the nature, setting, and effect of the expression.

Higgs clarifies that where the expression is simply the articulation of the belief in private, personal space, the bar for justified employer interference is high. It does not clarify what happens when expression moves into the workplace itself, into interactions with colleagues or service users, or into more aggressive or targeted forms of communication.

Practical Implications

For Workers

If you hold a belief that meets the Grainger criteria and your employer takes adverse action against you, the relevant questions are:

Does your belief qualify? It must be genuinely held, weighty, cogent, and compatible with human dignity. The threshold is not high, but it is real.
Was the employer's action because of, or materially influenced by, your belief or its expression? If the adverse action was genuinely about your conduct rather than your belief, the claim will fail at this stage.
If the action was belief-related, was it proportionate? This is where Higgs is most significant: remote, speculative, or disproportionate responses to out-of-work expression of belief are unlikely to be justified.

Workers dismissed or disciplined in circumstances resembling Higgs should consider a claim for direct discrimination under section 13 of the Equality Act 2010. The standard time limit for bringing an Employment Tribunal claim is three months less one day from the date of the act complained of, subject to ACAS early conciliation.

For Employers

Higgs does not make it impossible to discipline employees for social media activity. It does raise the bar significantly for dismissal in cases involving out-of-work expression of genuinely held beliefs. Employers should:

Consider whether the conduct is genuinely a manifestation of a protected belief before initiating disciplinary action.
Apply a proportionality analysis. Ask whether lesser sanctions, a formal warning, or a public statement distancing the organisation from the employee's personal views would adequately address the concern.
Avoid relying on generalised reputational risk without evidence of actual or concrete harm.
Document their reasoning carefully, particularly in cases where beliefs are contested or politically sensitive.
Review social media policies to draw a clear distinction between personal and professional accounts, and to ensure that any restrictions are framed around legitimate operational concerns rather than the content of beliefs. Policies that purport to regulate all online expression without reference to proportionality are more vulnerable to challenge after Higgs.
Train managers on the proportionality framework. Line managers making recommendations to HR are often the first point at which disproportionate responses are introduced into the disciplinary process.

The judgment does not reduce employers' ability to protect service users, pupils, or colleagues from harassment. What it limits is the use of dismissal as a first or reflexive response to controversial but private belief expression.

The Broader Picture: A Line of Cases Taking Shape

Higgs does not stand alone. It is the latest development in a line of authority that has been building since Grainger and that shows no sign of settling. Forstater established that gender-critical beliefs qualify for protection. Mackereth showed that qualification does not mean impunity for workplace conduct. Higgs now establishes that private, personal expression of a protected belief attracts strong protection and that disproportionate employer responses will not be excused by vague reputational concerns.

The tensions in this area are structural. The Equality Act 2010 protects multiple characteristics simultaneously. A school with LGBT pupils has legitimate interests in their wellbeing and inclusion. An employee has legitimate interests in holding and expressing her beliefs outside work. The Act does not resolve that tension by fiat; it requires courts and tribunals to work through it on the facts of each case, applying proportionality.

What Higgs adds to that framework is a clearer signal that the private/professional distinction matters, that length of unblemished service matters, and that the availability of lesser sanctions matters. Employers who treat dismissal as the default response to controversial belief expression, without asking whether anything less severe would do, are taking a significant legal risk.

Academic commentary, including a note in the Industrial Law Journal published after the judgment, has noted a deeper doctrinal question: the Court of Appeal's approach in Higgs (building on Page) effectively introduces a proportionality and justification analysis into direct discrimination under section 13, which the Equality Act normally does not permit. Unlike indirect discrimination under section 19, direct discrimination carries no built-in justification defence. The Court achieves proportionality review by a different route, using Article 9(2) ECHR to qualify what counts as treatment "because of" a protected characteristic. Whether this is a legitimate use of Convention rights or an uneasy structural workaround is a question only a future Supreme Court case is likely to resolve.

Higgs v Farmor's School [2025] EWCA Civ 109 is a landmark judgment for employment law, belief protection, and the relationship between private expression and professional consequences. It confirms that the law takes seriously the protection of genuinely held religious and philosophical beliefs, that expression of those beliefs in personal spaces attracts strong protection, and that employers who dismiss employees on speculative reputational grounds without working through a proper proportionality analysis do so at their legal peril.

The case sits within a broader evolution of belief jurisprudence in which the courts have steadily expanded the scope of protection while maintaining meaningful limits on what that protection actually permits. It does not resolve all tensions in this area: the conflicts between competing protected characteristics, the boundaries of acceptable workplace expression, and the treatment of more extreme forms of belief all remain live and contested questions.

What Higgs does establish, with the authority of a final Court of Appeal judgment, is that belief protection in the workplace is substantive and not merely formal, and that dismissal for who you are rather than what you do will not be easily justified.
